Pressing diaphragm and pressing filter plate for a compression type filter press

摘要

A pressing diaphragm and a pressing filter plate of a compression type filter press in which a surface of a main body of a pressing filter plate is covered with the pressing diaphragm, include: a projection member (6, 36, 46, 56, 66, 76, 86) provided on the surface; and a projection member mounting member (27, 37, 57, 67) capable of contacting the main body (3), provided in a rear surface at a position corresponding to the projection member, and for mounting the projection member thereon with a fixture (7). The projection member has a plurality of pillar portions (6a, 36a, 46a, 56a, 66a, 76a, 86a) mounted on the projection member mounting member and fitted in a through-hole (1a, 31a, 41a) of the pressing diaphragm (1, 31, 41, 51), a mounting hole (6b, 36b, 46b, 56b, 66b, 76b, 86b) penetrating through each of the pillar portions, and a long connecting plate portion (6d, 36d, 46d, 56d, 66d, 76d, 86d) for connecting the pillar portions with each other and regulating expansion of the pressing diaphragm fitted into a periphery of the pillar portions. The projection member mounting member has a mounting portion (27a, 37a, 57a, 67a) for mounting the fixture to be inserted into the mounting hole of each pillar portion of the projection member.
